Horning owners what amps have you used?

Dpe,
Audio Note Kits has a 20w Push Pull 300b Interstage Mono Amp as well. All of the products on the AN Kits site were built by Pete Fulton. If you don't have the time for your own build, give him a shout he can be found here http://www.digitalpete.net/. He is knowledgable and reasonable too.
Good Luck

Viva and mastersound make SET able to drive your loudspeakers load.

I use Art Audio Jota monos (Emission Labs 520 output tubes) to drive my Eufrodite Ultimate Zigmas, as I did on Agathon Ultimates before them, both have been great matches... I think the speakers see about 24 watts output maximum, but I've never gotten close to maximum gain on my preamp.

I think the extra power might just be giving these speakers a little extra jump, but couldn't swear to it, as I've certainly heard them both sound spectacularly good with less power- both at Jeff's loft and at several of his show set-ups.

Hope this helps.

Believe it or not, these speakers do well with some power. Or, at least, a lower power amp with some bottom end. Well, maybe it's not surprising, given the amount of woofer cone they have. The wrong amp will really show poorly, far worse than with a lot of loudspeakers, and the end result will be thin and harsh.

That being case, I don't recommend 300B amplifiers, not enough grunt. Try something else, and you'll likely wonder at how much music you were missing.

My Atma Sphere M60 and a friend's Transcendents were a terribly poor match. I haven't worked it all out, but OTLs work great with front loaded horns, but seemingly not at all with back loaded horns.

I get very nice results with my Dynaco ST70 and an el cheapo Chinese 6AS7G push-pull integrated. So far, the best I've heard has been the Deja Vu push-pull 2A3. That amp kept me and my non-audiophile headbanging buddy happy spinning things like Led Zeppelin or Kraftwerk at crazy volumes. Most surprising to me, my Jadis DA60 mates exceptionally well with them.

Trelja,
Dpe has already stated twice that he gets excellent results with his Thoress 300b, When it comes to 300b amplifiers there`s quite a range in terms of ultimate performance. Some have 'much' better transformers, stiffer power supplies and part quality than others.
Also much of the grunt/drive factor is influenced by the choice of driver tube. there are many variables that seperate 300b amps from average to outstanding.
To generalize is very in accurate.
Horning makes his own 300b amp, he must find them quite capable I`d assume. Some 300b amps would just be okay and there are others that would drive these Hornings to hell and back.
Best Regards,
